The genus Cyanoneuron is established to accommodate three Bornean and Sulawesi species previously placed in Myrioneuron . Two new species: C. grandiflorum and C. pedunculatum are described. All five species are illustrated. A survey of the character states including vegetative, inflorescence, floral, fruit, pollen, seed morphology and anatomy is given. The chromosome number has been counted for C. cyaneum, C. grandiflorum and C. pubescens. Cyanoneuron is tentatively included in the tribe Hedyotideae, but its affinity to genera inside this tribe is unknown.
